ELECTRIC LIGHTING SYSTEM FOR GAS OVENS, HEATERS OR THE LIKE Filed. Jan. 28, 1959 2 Sheets-Sheet 2 ATTORNEY United States Patent 3,075,126 ELECTRIC LIGHTING SYSTEM FOR GAS OVENS, HEATERS OR THE LIKE Sergio Quinciano Lopez Lois, Coucejal Miguel Pallares 33, Repacto Debeche, Guanabacoa, Havana, Cuba Filed Jan. 28, 1959, Ser. No. 789,696 4 Claims. (Cl. 317-83) One of the advantages of the lighting system of this invention consists in that it permits the instantaneous lighting of the burners of gas ovens, heaters or the like.

Another advantage of the lighting system of this invention is that it may be formed integral with the gas oven, heater or the like, or it may be formed as a separate attachment for the latter.

The present invention comprises an electric circuit consisting of a transformer, a vibrator Rumkorff spool or a coil, and a special switch for operating the system. The electric circuit may be operated as well by means of a vibrator spool of the required specifications ositioned, directly on the 110 or 220-v0lt electric system.

While both the vibrator Rumkorif spool and the transformer are well-known parts commonly used in numerous electric devices and therefore a detailed description of their structure is unnecessary, this is not the case with. the special switch of this invention. This special switch consists of a disc controller which connects the electric current upon operation of a notched disk mounted on the same shaft on which the disc controller is mounted. Said notched disk allows the switch contact and maintains the flow of electric current during the travelling of the disc controller, and once the lighting of some or all of the burners has been effected, said disk is urged back to its initial position by the action of a spring, whereupon the flow of electric current will again be discontinued and the system disconnected.

On the other hand, the high voltage electric current as produced by the transformer and vibrator Rumkorif spool assemblage is distributed by said switch to the several gas burners, to produce a sparking right above the burners and thereby light them up.

The invention is described with reference to the figures of the accompanying drawings, wherein:

FIGURE 1 is a side partly sectional view of the lighting system of this invention.

FIGURE 2 is a front partly sectional view of the lighting system of this invention.

FIGURE 3 is a side view of the base portion, the supports and the insulating circular piece carrying the conductors leading to the electrodes situated in the gas burners.

FIGURE 4 is a perspective detailed view of the insulating circular piece shown in FIG. 3.

FIGURE 5 is a detailed view of the electric current switch.

FIGURE 6 is a detailed view of the special switch of this invention.

The lighting system of this invention comprises a manually operable disc control piece I mounted on a shaft 2 which is rotatably mounted on supports 3 and 4 of said shaft 2, the latter being positioned on an insulating base portion 5. Said shaft 2 has wound thereabout a spring 6 which is secured at one end to the disc control piece 1 and at the other end it is secured to the support 3 so as to thereby urge the notched disk 7 to take its initial position as shown in FIG. 2. Said notched disk 7 is mounted concentrically on the shaft 2 and has at its lower portion a notch 7 to receive therein a wheel 8. When the lighting system is disconnected, said wheel 8 is lodged in said notch 7, and when it is desired to connect the lighting system, the disc control piece 1 is rotated, whereupon the disk 7 will likewise rotate and the wheel 8 will leave the notch 7. Said wheel 8"is mounted on a small insulating bracket support 9 (FIG. 5) positioned on an inclined metal piece 10 which has its front portion con:

nected to a conductor 11 leading to the or 220-volt electric current supply source and has at its rear portion adjacent the front end a spring 12 and near its other end it has a platinum or metal terminal 13 which is in contact with another platinum or metal terminal 14 to close the circuit. Said metal terminal 14 is connected by a conductor to the primary of transformer 15 which has its secondary connected by a conductor 16 to the vibrator Rumkorif or induction coil 17.

The transformer 15 has another conductor 18 leading to the 110 or 220-volt electric current supply source to close the primary circuit, and another grounded conductor 19 to close the secondary circuit. The induction coil or vibrator Rumkorif spool 17 has a conductor 20 to ground and another conductor 21 for connecting the high voltage current produced by said induction coil or Rumkorif spool 17 to the arm 22 which yieldingly contacts the.

centre of the hollow metal piece 23 fixedly mounted on an insulating plate or disk 24 mounted on said shaft 2, said insulating plate or disk 24 being movable together with the disc controller 1 and the notched wheel 7.

The hollow metal piece 23 comprises a metal casing enclosing a small spring 25 and two rods 26 on which the metal wheel 27 is mounted. Said metal wheel 27 rotates about the inner face of the insulating circular piece 28.

About the inner face of said insulating circular piece 28 is arranged a plurality of metal plates 29, 30, 31, 32, 33,

34, and 35 secured thereto by screws passing across the insulating circular piece 28, and the end of each screw has a nut acting as a terminal having connected thereto a conductor leading to each of the burners to cause a spark to fly off from the electrodes as shown in FIGURE 4 which are insulated by porcelain insulators from the body of the burners right at the burners gas outlet, and thereby ignite the gases.

It is obvious that changes may be made in the lighting system of this invention without thereby altering the essential character of the invention, which is such as defined by the appended claims.
